A Guide to Estate Planning for Unmarried Couples

Estate planning for unmarried couples presents a unique set of challenges that married partners simply don’t face. Without the legal protections that marriage automatically confers — such as spousal inheritance rights and joint tax treatment — unmarried couples must be especially intentional about structuring their plans. 

The good news is that there are well-established legal tools and strategies that cancan be used to address planning considerations for unmarried couples and help protect both partners and reflect their shared wishes.

A well-structured estate plan for unmarried couples typically addresses several key areas:

• Wills and beneficiary designations
• Powers of attorney
• Healthcare directives
• Trusts
• Titling and ownership structures
• Tax planning
• Long-term care and incapacity planning

If you and your partner are ready to take a closer look at where your plan stands, schedule a conversation with the team at Avidian Wealth Solutions. Our advisors work closely with clients who are navigating the nuances of estate planning for unmarried couples and can help you

evaluate and develop a plan that reflects your goals and lifestyle.

7 estate planning options unmarried couples can consider

Without the automatic legal protections that come with marriage, unmarried couples need to be proactive about putting the right documents and structures in place. Each of the strategies below serves a distinct purpose, and together they can form the foundation of a thoughtful, comprehensive plan.

Wills and beneficiary designations

A will is one of the most fundamental documents in any estate plan — and for unmarried couples, it’s especially critical. Without a valid will, state intestacy laws typically direct assets to biological relatives, not a long-term partner. A clearly drafted will allows you to name your partner as a beneficiary and designate how your assets should be distributed upon your death.

Beneficiary designations on accounts such as IRAs, 401(k)s, and life insurance policies function independently of a will, which means they require their own careful attention. These designations supersede whatever a will may state, so reviewing and updating them regularly is an important part of determining whether your overall plan remains aligned with your intentions.

Powers of attorney

A financial power of attorney grants your partner the legal authority to manage your financial affairs if you become unable to do so yourself. Without this document, an unmarried partner has no automatic right to access accounts, pay bills, or make financial decisions on your behalf — even after years or decades together.

For high-net-worth individuals with complex financial lives, a durable power of attorney can be particularly important. It can be structured to take effect immediately or only upon incapacity, and it can be tailored to cover specific assets or broad financial authority. Consulting with estate planning advisors who understand the full scope of your financial picture can be an important

step to help as you draft a plan that reflects your intentions.

Healthcare directives

A healthcare directive — which may include a living will and a healthcare proxy or medical power of attorney — allows you to document your medical preferences and designate your partner to make healthcare decisions on your behalf. Without these documents, hospitals and medical providers may default to next of kin, which in most states means biological family members, not an unmarried partner.

These documents become especially important in emergency situations where decisions must be made quickly. It’s worth noting that Texas is one of a handful of states that recognize common-law marriage — formally referred to as a declaration of informal marriage — which may carry additional legal rights and implications for couples who qualify.

Trusts

Trusts if structured properly can offer a level of control and flexibility that a will alone typically cannot. For unmarried couples, a revocable living trust can allow assets to transfer to a partner outside of probate, which can be both faster and more private than the probate process. Irrevocable trusts may serve additional purposes, including asset protection and certain tax planning strategies.

Estate planning techniques for high-net-worth families often lean heavily on trust structures precisely because of their versatility. A well-designed trust can dictate not just who receives assets, but when and under what conditions — a meaningful distinction when substantial wealth, real estate, or business interests are involved. Trusts can also help address potential family disputes, which is especially relevant for unmarried couples whose partners may not be recognized by default under state law.

Titling and ownership structures

How assets are titled has a direct effect on what happens to them at death — and for unmarried couples, the wrong titling can undermine even the most carefully drafted estate plan. Joint tenancy with right of survivorship, tenancy in common, and community property each carry different implications for how ownership transfers and what rights each partner holds during life.

Reviewing and intentionally structuring how property, investment accounts, and other major assets are held is a step that often gets overlooked, particularly as wealth grows and accumulates across multiple accounts and asset classes. Estate planning for wealthy individuals frequently requires a detailed audit of existing titling to confirm it aligns with the broader plan — because a mismatch between titling and intent can create unintended outcomes that are difficult or impossible to reverse after the fact.

Tax planning

Unmarried couples face a notably different tax landscape than married couples. They do not have access to the unlimited marital deduction, cannot take advantage of the portability of the estate tax exemption between partners, and may face gift tax considerations when transferring assets to one another during life. With potential estate tax law changes on the horizon, the stakes around proactive planning have become even more significant for high-net-worth individuals.

Strategies such as annual gifting programs, irrevocable life insurance trusts (ILITs) and charitable giving vehicles may all warrant consideration depending on the size and structure of your estate. Because tax planning intersects closely with both legal structures and investment strategy, it’s an area where coordination between your attorney, CPA, and estate planning financial advisor is particularly valuable.

Long-term care and incapacity planning

Planning for the possibility of incapacity or the need for long-term care is an often-deferred conversation — but for unmarried couples, the absence of automatic legal standing makes it even more pressing. Navigating uncomfortable conversations about family wealth and the future can feel daunting, but addressing these scenarios in advance may be an important step for

partners to consider..

Long-term care insurance, disability income coverage, and clearly documented incapacity plans can all help a partner step in and manage care decisions without unnecessary legal barriers. For couples with significant assets, it’s also worth considering how the cost of extended care might affect the overall estate and whether structures are in place to help manage that exposure without depleting wealth intended for the surviving partner or future generations.

Estate planning for unmarried couples — FAQs

What happens if my partner dies and we are not married in Texas?

If your partner dies without a will in Texas, state intestacy laws will direct their assets to biological relatives — not to you as an unmarried partner. This means that without proper estate planning documents in place, you may have little to no legal claim to shared property, accounts, or other assets. Taking steps to establish clear beneficiary designations and a valid will is one of the most important ways to protect both partners.

Do unmarried couples have the same inheritance rights as married couples in Texas?

No — unmarried couples do not have the same automatic inheritance rights as married spouses under Texas law. Without a will or other estate planning documents, a surviving partner is not entitled to any portion of their partner’s estate by default. This is one of the primary reasons that thoughtful financial provision for unmarried couples requires proactive legal planning rather than relying on state law defaults.

Can an unmarried partner make medical decisions for me in Texas?

Not automatically. Without a properly executed healthcare directive or medical power of attorney, Texas hospitals and providers are generally required to defer to next of kin — which typically means biological family members, not an unmarried partner. Putting these documents in place is a straightforward and important step for any unmarried couple.

Is estate planning different for high-net-worth unmarried couples?

The foundational documents are the same, but the complexity increases considerably as the size and structure of an estate grows. High-net-worth unmarried couples often need to account for additional considerations such as trust structures, gift and estate tax exposure, business interests, and multi-generational wealth transfer.Working with legal and financial advisors may be an important part of the planning process and can help support the development and implementation of an estate plan.

Protecting what matters starts with a conversation. Let’s talk.

Unmarried couples have more options than many people realize — but those options only work if the right documents and structures are in place before they’re needed. Estate planning for unmarried couples requires a level of intentionality that goes beyond what the law provides automatically, and the stakes are too high to leave to chance.
