When Family Wealth Is Held in One Partner’s Name
One partner can own the family home, control the investment accounts and manage the household’s finances while the other depends on those assets for everyday security. Marriage, inheritance rights and trusts provide different forms of protection, but none guarantees immediate access to money when circumstances change.
Families can accumulate considerable wealth without both partners having equal legal rights to it. The family home belongs to one spouse, investment portfolios remain in accounts opened before the marriage, and shares in the family business sit under the founder’s name. Both partners enjoy the income and lifestyle those assets provide, although only one has direct authority to manage them.
Such arrangements often develop over many years. One partner builds a business or manages investments while the other reduces paid employment, raises children or takes responsibility for the household. The family’s finances operate as a single economic unit, even though its assets remain legally separate.
Difficulties emerge when the person controlling those assets dies, loses mental capacity or the relationship ends. The surviving or dependent partner’s financial position then depends on ownership records, matrimonial-property rules, inheritance law and the arrangements made while both partners were able to act.
Marriage Does Not Automatically Mean Joint Ownership
In Switzerland, the statutory matrimonial-property regime is participation in acquired property, unless spouses have agreed to another arrangement. Under Articles 196–215 of the Swiss Civil Code, the law separates each spouse’s individual property from assets acquired during the marriage.
Property owned before marriage, along with inheritances and gifts received during marriage, generally remains individual property. Employment income and other qualifying acquisitions form part of the acquired property that is accounted for when the matrimonial regime ends. Income generated by individually owned property is generally classified as acquired property under the ordinary regime.
Each spouse normally manages their own assets during the marriage. Sharing household expenses or enjoying income from an investment portfolio does not automatically transfer ownership of the underlying securities.
When the marriage ends through divorce or death, the matrimonial-property regime determines how the spouses’ acquired property is divided. Under the ordinary Swiss regime, each spouse generally has a claim to half the other spouse’s net acquisitions, subject to statutory rules and any valid matrimonial agreement.
Spouses can consequently hold a financial claim without appearing as the registered owner of a particular asset. Establishing the entitlement involves examining the source of funds, ownership records, liabilities and changes in asset values. Contributions towards property owned by the other spouse can also give rise to claims under the applicable provisions of matrimonial-property law. These calculations become more complicated when most of the family’s wealth is invested in a privately owned company. A monetary entitlement arising from the matrimonial-property settlement does not automatically give the recipient company shares or voting rights. The settlement can create an obligation that the owning spouse or estate must satisfy through cash, financing or other assets.
The Family Home Can Create a False Sense of Security
A couple can live in the same house for decades, contribute to its maintenance and regard it as their permanent family home, although only one partner appears on the title. Marriage, financial contributions and occupation can give the other partner legal protection, but the scope of that protection depends on the applicable law and the ownership arrangements.
In England and Wales, property held jointly can be owned as a beneficial joint tenancy or a tenancy in common. Where two people own a home as beneficial joint tenants, the surviving owner automatically acquires the deceased owner’s interest through survivorship. The deceased cannot leave that interest to another beneficiary through a will.
Tenants in common hold separate beneficial shares. Each owner’s share becomes part of their estate when they die and passes under their will or the applicable intestacy rules. The position of an unmarried partner is less secure when the property belongs exclusively to the other person. Cohabitation does not generally create the inheritance rights enjoyed by spouses and civil partners in England and Wales. A surviving partner can face uncertainty over continued occupation despite having lived in the property for many years and contributed to household costs.
Financial contributions can support claims to beneficial ownership, while certain surviving cohabitants can seek financial provision from an estate under the Inheritance (Provision for Family and Dependants) Act 1975. These claims depend on legal conditions and evidence. They are not equivalent to holding a clearly documented ownership interest or an automatic inheritance entitlement.
Families can address some of these risks through appropriate ownership arrangements, wills and documented rights of occupation. The legal treatment must reflect the circumstances of the property, including existing mortgages, other beneficiaries and the consequences of transferring ownership.
Inheritance Rights Do Not Guarantee Immediate Liquidity
Death creates a separate financial problem when a family has considerable assets but limited money available for immediate expenditure. A surviving spouse can be entitled to a substantial share of an estate while remaining unable to operate the deceased’s individually held bank accounts until the necessary administration requirements have been satisfied. Investment portfolios, properties, private-company interests and insurance contracts can follow different procedures before ownership or proceeds become available.
Under Swiss law, the matrimonial-property settlement generally precedes the distribution of the deceased spouse’s estate. The surviving spouse’s entitlement under the matrimonial regime must be established before the inheritance is divided among the heirs.
In England and Wales, jointly owned assets passing by survivorship are treated differently from assets held solely by the deceased. A person authorised to manage an account during the owner’s lifetime does not necessarily retain that authority after death. A lasting power of attorney, for example, ends when the donor dies, leaving the estate’s personal representatives responsible for administering assets within their authority.
The time needed to establish those rights and complete estate administration can create pressure on the surviving household. Mortgage payments, property maintenance, healthcare costs and school fees continue, while a family business can require additional working capital or debt repayments. A family whose wealth consists primarily of real estate and private-company shares can be asset-rich but short of readily available funds. Even a sizeable inheritance entitlement does not guarantee that the beneficiary can obtain cash without selling assets, arranging finance or waiting for estate administration.
Maintaining appropriately funded accounts under each partner’s own control can reduce dependence on those procedures. Life insurance and other contractual benefits can provide additional liquidity, depending on their beneficiary arrangements and legal treatment.
Incapacity Requires Its Own Financial Arrangements
Loss of mental capacity can interrupt a family’s financial affairs long before inheritance becomes relevant. The partner who ordinarily manages investments, pays expenses or directs a business can become unable to authorise transactions following serious illness or injury. Marriage alone does not give one spouse unrestricted authority over the other’s individually owned assets. In England and Wales, a registered property and financial affairs lasting power of attorney allows an appointed person to act within specified powers. The appointment can cover banking, investments, bills and property transactions. The attorney must comply with the legal duties attached to the role and act in the donor’s interests rather than treating the property as their own.
Swiss law provides for an advance care directive, through which a person can appoint someone to manage specified personal, financial and legal affairs if they lose capacity. Under Article 374 of the Swiss Civil Code, spouses and registered partners can also have statutory representation rights when the applicable conditions are met and no other relevant arrangement takes precedence.
Those statutory rights cover defined activities, including ordinary financial administration. More extensive transactions, such as certain property dealings, can require authorisation from the adult protection authority.
A partner who has traditionally relied on informal access to accounts can discover that the bank requires formal evidence of authority before permitting transactions. The position becomes more complicated when the family has assets held by institutions in several countries, each applying its own documentation and recognition requirements.
A Swiss advance directive, an English lasting power of attorney and a corporate signing mandate serve different legal purposes. Families with international assets need to establish which documents their banks, trustees and companies will accept and whether those arrangements remain operational following incapacity.
Trust Beneficiaries Do Not Necessarily Control Trust Wealth
Trusts introduce another legal relationship between family wealth and the individuals who depend on it. A spouse can be named as a beneficiary without owning the assets held by the trustees. Their rights depend on the trust instrument, the governing law and the nature of the beneficial interest.
English trust law distinguishes between arrangements giving beneficiaries defined entitlements and those allowing trustees discretion over distributions.
Under an interest-in-possession trust, a beneficiary can be entitled to receive income generated by the trust assets while the underlying capital is preserved for other beneficiaries. A surviving spouse, for example, can receive investment income throughout their lifetime while the trust provides for the capital to pass to the children after their death.
A discretionary trust operates differently. Trustees decide whether to distribute income or capital, to whom and in what amounts, within the powers established by the trust instrument. A spouse included among the discretionary beneficiaries generally cannot demand a particular payment merely because the family regards the trust assets as part of its wealth.
Discretionary beneficiaries retain rights relating to the proper administration of the trust, but those rights do not give them unrestricted access to its capital. Trustees must exercise their powers in accordance with the trust instrument and their fiduciary obligations, taking account of the interests they are required to consider.
A partner accustomed to receiving regular trust distributions can become financially dependent on payments that are not legally guaranteed. Trustees can change the amount and timing of distributions in response to beneficiary needs, investment performance and the requirements of the trust.
This creates an issue when the person who established the trust also controls most of the family’s other wealth. The dependent spouse can have no direct ownership of the trust assets and limited resources outside the structure.
Letters of wishes can communicate the settlor’s intentions concerning distributions and family support, but they are generally not binding on trustees. Families expecting a trust to support a surviving spouse need to examine the actual rights granted by the trust deed, the discretion available to trustees and the assets accessible independently of the structure.
Cross-Border Families Face Several Sets of Rules
International families frequently hold assets under legal arrangements established in different countries. A couple living in Switzerland can own residential property in England, hold investments through a foreign bank and benefit from a trust governed by English law.
Their matrimonial-property rights, succession arrangements and trust interests require separate legal analysis. The laws governing those relationships can differ, even when the family treats its wealth as a single portfolio.
Switzerland recognises trusts under the Hague Trust Convention, which entered into force for the country in July 2007. Recognition allows a trust governed by foreign law to be acknowledged within the Swiss legal system, but it does not automatically displace applicable matrimonial-property or inheritance rights.
The interaction becomes more complex when trust assets were transferred by a spouse whose family remains connected to Switzerland. The validity and legal consequences of the transfer, possible claims by other family members and the treatment of the assets for succession purposes require examination under the applicable rules.
The European Succession Regulation provides a framework for international inheritance involving participating EU member states. It generally applies the law of the deceased’s habitual residence to succession, while permitting a person to choose the law of a country whose nationality they hold.
The Regulation does not bind Switzerland or the United Kingdom. It also excludes certain matters, including matrimonial-property regimes, the creation and administration of trusts and succession taxation, from its substantive scope. A family whose assets extend across these jurisdictions must therefore consider the relevant rules separately.
Tax residence adds another layer. Since 6 April 2025, the United Kingdom has used a long-term residence framework for determining the exposure of foreign assets to inheritance tax. The rules can affect internationally mobile families and certain trust arrangements, depending on residence histories, the location of assets and the circumstances in which property was settled.
A will prepared in one country, a matrimonial agreement signed in another and a trust governed by foreign law do not automatically form a coordinated succession plan. Their interaction has to be assessed against the family’s ownership arrangements, residence, nationality and the location of its assets.
Financial Access Needs Its Own Arrangements
A review of family wealth frequently begins with the value of assets, their ownership structures and the intended succession between generations. The financially dependent partner also needs a clear understanding of which resources remain available when the person ordinarily managing the money can no longer act.
The first task is to identify what each partner owns, what they have authority to manage and which assets require another person’s consent before they can be used. Individually held savings, joint accounts, investment income, insurance benefits and trust distributions can provide different levels of access and legal protection.
The family can then examine those resources alongside its financial commitments. Regular household expenditure, property costs, healthcare, education and debt obligations need to be met regardless of how long an estate administration or legal-authorisation process takes.
Longer-term arrangements involve several legal instruments. Wills determine the intended distribution of estate assets within the applicable succession rules, matrimonial agreements regulate specified property rights between spouses, and powers of attorney or their local equivalents establish authority during incapacity. Trust instruments define trustee powers and beneficiary rights.
These documents need to operate together. A will does not replace an incapacity mandate, a discretionary trust does not guarantee regular distributions, and a matrimonial-property entitlement does not automatically provide liquid funds.
The review also needs to account for wealth concentrated in assets that cannot readily be divided or sold. Privately held businesses, large property holdings and investments subject to contractual restrictions can leave a surviving partner with a valuable legal claim but few immediately available resources.
Clear ownership records, appropriately drafted legal instruments and sufficient independently accessible funds provide a firmer basis for financial continuity.
A family balance sheet showing considerable net wealth does not establish that both partners can use it. Their financial security rests on the rights they actually hold, the funds they can access and the arrangements that remain operational after death, incapacity or separation.
