Building a life together without being legally married can feel natural, secure, and simple. You split bills, share responsibilities, and plan your future around each other. But what happens to unmarried couples when one partner becomes incapacitated or passes away? Many couples discover too late that the law does not treat emotional commitment the same way it treats marriage.
According to the South Dakota Unified Judicial System’s FY 2025 Annual Report, circuit court probate filings reached 2,346 cases in the most recent reporting period. As these matters increase, contested estates are taking longer to resolve, leaving partners locked out of shared bank accounts, unable to manage property, and vulnerable to relatives who suddenly gain legal authority.
ND Estate Services helps unmarried couples create trust-based plans built around privacy, control, and continuity. Our team reviews how assets are titled, aligns beneficiary forms, and guides trust funding so partners do not lose access to shared homes or savings during difficult moments. We focus on minimizing conflict and helping couples protect the life they built together.
In this blog, we’ll review 7 practical estate planning tips for unmarried couples, strategies that prevent family disputes, keep assets out of the courtroom, and ensure your partner can continue managing financial decisions without interruption.
Quick Answer: Do Unmarried Partners Inherit in South Dakota?
No. When someone dies without a plan, South Dakota follows the Uniform Probate Code. Under SDCL 29A-2-103, assets pass to children, parents, or siblings. Unmarried partners are not included in the statutory order. If assets are not transferred into a trust, they enter probate under SDCL 29A-3-101, placing relatives in control and creating access delays you never planned for.

7 Essential Tips for Estate Planning for Unmarried Couples
1. Build a Revocable Living Trust to Avoid Probate
A revocable living trust allows your partner to receive assets privately without court involvement. Without one, probate under SDCL 29A-3-101 can freeze accounts, delay access to funds, and expose financial records to relatives who may not approve of your relationship.
Imagine your partner needing money to pay the mortgage but being told the court must authorize every transaction first. ND Estate Services designs a trust that transfers control immediately, preserves privacy, and avoids contested hearings.
If something happened tomorrow, would you want your partner waiting for permission from a judge?
2. Align Beneficiary Designations Across All Accounts
Beneficiary forms override wills and trusts. If outdated, retirement accounts and life insurance can go to an ex partner, parent, or sibling. South Dakota courts enforce the last signed form, even if an outdated beneficiary contradicts new wishes. This can create sudden financial hardship.
ND Estate Services performs a beneficiary audit, mapping every account to your trust to create consistency. Picture your partner discovering a large account is still directed to a former partner simply because no one noticed. This common oversight can be prevented in one planning session.
When last did you check your beneficiary listings?
3. Review How Your Home and Property Are Titled
Joint tenancy and tenancy in common transfer property differently. In tenancy in common, your share may go to relatives who insist on selling the home. Under SDCL 30-21-3, a transfer-on-death structure can move real estate privately if aligned with a trust.
ND Estate Services reviews your deed to prevent conflicts with siblings or parents who gain a legal stake through intestacy. Imagine grieving while negotiating with someone who never supported your relationship. A small change today prevents a forced sale tomorrow.
Whose voice would a court listen to without clear titling?
4) Include Guardian Instructions for Children and Pets
Without a written nomination, guardianship decisions default to relatives under SDCL 29A-5-201. A relative who disagrees with your parenting style could step forward and gain control. Pets are treated as property unless directives are built into a trust. ND Estate Services places guardianship and pet care instructions in documents that judges recognize.
Picture someone claiming your pet because the law considers them property. Strong written direction ensures the person who actually knows your child or pet takes responsibility.
Who would the court select if there were no instructions?
5. Consider an Irrevocable Trust for Asset Protection
An irrevocable trust can shield assets from certain risks. Couples use this when long-term care costs or inheritance disputes might undermine a partner’s security. These trusts limit control but protect property by transferring ownership before a crisis strikes.
ND Estate Services educates you on the timing and tradeoffs, then collaborates with tax professionals for proper structure. Imagine needing medical care and discovering your partner may need to sell your home to cover expenses. Planning prevents rushed decisions.
If your health changed next year, would your partner be protected?
6. Fund the Trust Correctly to Make It Work
Signing a trust does not move assets automatically. Every deed, account, and beneficiary form must be retitled or assigned. If asset funding is incomplete, property may enter probate under SDCL 29A-3-101, making your partner request permission to manage your belongings. ND Estate Services provides funding checklists, custodian coordination, and follow through so the plan works in real life.
Imagine believing you protected everything, only to learn the trust was empty and relatives now have rights. Funding is the difference between theory and protection.
Are your assets actually pointing to your trust today?
7. Review and Update Your Plan Regularly
Life changes quickly. New homes, business growth, children, and shifting relationships can disrupt old instructions. Courts follow documents, not informal agreements. ND Estate Services performs ongoing reviews to ensure asset lists, deeds, and beneficiary forms stay current. Imagine buying a new property last year but never transferring it into your trust.
That property can be forced through probate. Updating prevents accidental inheritance by the wrong person.
