How Does a Second Marriage Affect Estate Planning?

Remarriage reshapes both families and finances, introducing new obligations and potential legal complications. Significantly, marriage automatically cancels any existing will unless it was made with the new marriage in consideration. This means that, without updating your estate planning documents, your assets could be distributed according to intestacy rules, rather than your wishes.

A second marriage naturally brings together different relationships, priorities and dependents. If you have children from a previous relationship, own property jointly or plan to support a new partner, reviewing your estate arrangements becomes essential to ensure your assets are distributed according to your wishes. Here, we explore how remarriage affects wills, inheritance and probate, and why consulting with will disputes solicitors can help prevent family conflict while protecting your intentions.

Marriage revokes your previous will

Under English law, marriage automatically invalidates an earlier will unless that document clearly states it was made in anticipation of the marriage. If you fail to make a new will, your estate will be distributed under the intestacy rules, which prioritise your new spouse. This can unintentionally exclude children from a previous relationship.

Without specific planning, it is possible your new spouse could inherit your entire estate (depending on its size), leaving your children without provision. Seeking expert advice from our team of estate planning solicitors provides you with security and peace of mind that each person you wish to provide for is recognised. Further, having a valid will can act as a safeguard to prevent disputes that often arise when inheritance expectations differ within blended families.

Stepchildren and blended family arrangements

Stepchildren do not automatically inherit under the intestacy rules. They must be explicitly named in a will to receive any inheritance. In blended families, this can become a source of tension, particularly where there are competing expectations between biological and stepchildren.

Disputes may also occur where adult children believe a new partner has exerted undue influence, or where they feel excluded from their parent’s estate. Clearly structured and legally sound estate planning helps maintain fairness and prevents misunderstandings.

Using trusts to balance interests

Trusts are a practical tool for protecting both your new spouse and children from a previous relationship. A life interest trust, for example, can allow your spouse to benefit from income or property during their lifetime, while eventually passing the capital to your children.

Trusts can also be used to:

  • Preserve family property and inherited wealth.
  • Ringfence assets intended for future generations.
  • Mitigate Inheritance Tax.
  • Formalise intentions to prevent legal disputes.

Professional legal advice is recommended when establishing a trust to address the various tax and legal considerations involved.

Joint assets and nominations

Some assets fall outside the control of a will and are transferred automatically. Property held as joint tenants passes to the surviving owner under the right of survivorship, regardless of what a will says. If you wish your share to be inherited by someone else, the ownership should be converted to a tenancy in common.

Pension funds and some life insurance policies are also distributed based on nomination forms or expressions of wishes. These need to be reviewed regularly, particularly after remarriage or divorce, to avoid funds being paid to unintended recipients. Joint bank accounts follow similar rules to property held as joint tenants, passing directly to the surviving account holder and not forming part of the deceased’s estate.

Preventing will disputes

A second marriage often creates overlapping financial expectations between spouses, children and stepchildren. When a will is outdated, ambiguous or omits someone who was financially dependent on the deceased, claims may arise under the Inheritance (Provision for Family and Dependants) Act 1975.

Legal disputes can also stem from informal promises or gifts made during a lifetime that are not reflected in the will. Where these disputes do occur, a solicitor can help you reach a resolution through alternative dispute methods such as mediation, or litigation where required.

By keeping estate plans current and transparent, you can reduce the likelihood of disputes and protect your family’s financial security.
