Yes. State intestacy laws are built for married spouses, meaning that without a plan your assets default to your legal relatives—not your partner. Unless you’ve formally registered a partnership your state recognizes, your survivor would inherit nothing; bank accounts, real estate, and personal items would pass to your family of origin. Drafting a Will, creating a Revocable Living Trust, updating beneficiary designations, and signing Powers of Attorney let you put your partner first and sidestep the gaps in the default rules.
