Situations
Estate Planning for Unmarried Partners
Simple explanation
Unmarried partners often lack the default inheritance, medical priority, tax, and property rights available to spouses, so coordinated documents and title are especially important.
- Intestacy favors legal relatives, not partners
- Intestacy generally favors legal relatives rather than an unmarried partner.
- Each document covers a different gap
- A will, trust, beneficiary forms, health documents, and property agreements serve different roles.
- Marital tax benefits depend on legal marriage
- Federal marital transfer-tax benefits generally depend on legal marriage.
- Put shared-home terms in writing
- Shared-home expenses, buyout rights, and occupancy should be documented deliberately.
The four parts of a working plan
- People Identify the owner, decision-makers, fiduciaries, and beneficiaries.
- Property Map title, contract rights, debts, tax attributes, and practical access.
- Documents Coordinate wills, trusts, powers, directives, and beneficiary forms.
- Review Revisit the plan after life, ownership, law, tax, or relationship changes.
Go deeper
Unmarried partners start without the default protections spouses have. The sections below cover inheritance, medical priority, tax and the shared home.
Who typically explores it
Long-term partners who have not married, couples who co-own a home without a written agreement, and partners who want each other at the hospital bedside.
Tax lens
Unmarried partners cannot use the unlimited marital deduction, so large transfers between them draw on the annual exclusion ($19,000 per recipient in 2026) and the lifetime exclusion. Adding a partner to the deed of a home can itself be a taxable gift.
Common mistakes
Assuming cohabitation creates inheritance rights
Adding joint title without considering tax and creditor effects
