Estate Planning After Divorce and Remarriage: What Changes and What Needs to Be Fixed

Divorce and remarriage are among the most disruptive events in an estate plan. Assets get divided, beneficiary designations become outdated, trust provisions create unintended consequences, and new relationships create competing interests. Most people make changes to their wills — and miss everything else.

What Divorce Actually Does to an Estate Plan

In most states, divorce automatically revokes provisions in a will that benefit a former spouse. But it does not revoke beneficiary designations on retirement accounts, life insurance policies, or jointly held assets. It does not terminate trust provisions. It does not change who holds a power of attorney or a health care proxy.

The result is often a post-divorce estate plan that says one thing and the rest of the documents say another — creating exactly the disputes the documents were designed to prevent.

The Beneficiary Designation Problem

Retirement accounts and life insurance policies pass by contract, not by will. If you updated your will after the divorce but forgot to change the beneficiary designation on your 401(k), your former spouse — or their estate — may receive those assets regardless of what the will says.

Updating beneficiary designations after a divorce is urgent and non-negotiable. It should happen before any other estate planning update.

Trusts Created During the Marriage

Irrevocable trusts created during a marriage — particularly SLATs or other trusts that benefit a spouse — require careful analysis after divorce. A SLAT that was funded to benefit a former spouse may continue to do so, depending on how the trust is drafted. In some cases, the divorce may allow the trustee to redirect distributions; in others, it may not.

Reviewing all irrevocable trusts with counsel immediately after a divorce is essential.

Blended Family Estate Planning

Remarriage creates its own estate planning complexity: how to provide for the new spouse while also protecting assets for children from a prior marriage. Qualified terminable interest property (QTIP) trusts, pre-nuptial agreements, and separate property designations are all tools used to address these competing interests.

Blended family planning is an area where generic estate planning forms are particularly dangerous. The interactions among family members, the nature of the assets, and the history of prior planning require a customized approach.

The Tax Implications

Divorce can also have significant estate tax consequences. The unlimited marital deduction — which allows assets to pass to a U.S. citizen spouse free of estate tax — is no longer available after divorce. For large estates, this changes the entire tax planning picture and requires a fundamental review of the overall strategy.
