Updating Your Estate Plan: 5 Life Events That Require Immediate Action

Thayer Partners Thayer Partners February 17, 2026

Your estate plan isn't a one-and-done document—major life changes demand immediate updates to protect your legacy and ensure your wishes are honored.

Marriage or Divorce: When Your Family Structure Changes Everything

Marriage and divorce represent two of the most significant shifts in your family structure, and both demand immediate attention to your estate plan. When you marry, your new spouse may not automatically inherit what you intend unless your documents reflect this union. Conversely, failing to update your estate plan after divorce could result in your ex-spouse retaining rights you never intended them to have.

Consider the implications: beneficiary designations on retirement accounts, life insurance policies, and transfer-on-death accounts often supersede what's written in your will. If your ex-spouse remains listed, they'll receive those assets regardless of your current wishes or new family situation. Beyond beneficiary changes, you'll need to review powers of attorney, healthcare directives, and trustee appointments to ensure the right people hold decision-making authority.

For those entering a second marriage or blended family situations, the complexity multiplies. You may need to balance providing for your new spouse while protecting inheritances for children from a previous relationship. Prenuptial agreements, qualified terminable interest property (QTIP) trusts, and carefully structured estate plans become essential tools for honoring commitments to all family members while preventing future conflicts.

The Arrival of Children or Grandchildren: Protecting the Next Generation

The birth or adoption of a child fundamentally changes your estate planning priorities. Suddenly, you're not just planning for asset distribution—you're ensuring your children will be cared for, educated, and protected if something happens to you. Without proper planning, courts will decide who raises your children, and that guardian may not align with your values or parenting philosophy.

Establishing guardianship provisions is your first priority, but comprehensive planning goes further. You'll want to create trusts that protect assets for minor children, specify how and when they receive inheritances, and appoint trustees who will manage funds responsibly until your children reach appropriate ages. Many parents stagger distributions—perhaps providing access at ages 25, 30, and 35—to protect young adults from inheriting substantial wealth before they're financially mature.

As your family grows with grandchildren, your estate plan should evolve again. You may want to establish educational trusts, create skip-generation transfers to minimize estate taxes, or update beneficiary designations to include these new family members. Grandparents often use estate planning to instill values, support education, and create lasting legacies that extend beyond their lifetime. Regular reviews ensure every member of your growing family is protected according to your current wishes.

Significant Wealth Changes: When Your Financial Landscape Shifts

Substantial increases or decreases in wealth require corresponding adjustments to your estate plan. Perhaps your business sold for a significant profit, you received an inheritance, investment portfolios appreciated dramatically, or conversely, market downturns reduced your assets considerably. These shifts affect everything from tax strategies to beneficiary provisions to asset protection measures.

Increased wealth often triggers estate tax concerns that previously weren't relevant. High net worth individuals need sophisticated strategies—irrevocable life insurance trusts, charitable remainder trusts, family limited partnerships, or grantor retained annuity trusts—to minimize tax burdens and maximize what transfers to heirs. What worked when your estate was valued at $2 million won't suffice when it reaches $10 million or $50 million.

Conversely, financial setbacks require recalibration. You may need to adjust expectations about what beneficiaries will receive, restructure trusts to reflect current reality, or prioritize which assets go to which heirs. Business owners who've experienced significant valuation changes—whether growth or contraction—need succession plans that accurately reflect current business worth and structure. Your estate plan should always mirror your actual financial situation, not outdated assumptions from years past.

Death or Incapacity of Key Players: Updating Your Trusted Circle

Your estate plan relies on specific individuals to execute your wishes—executors, trustees, powers of attorney, healthcare proxies, and guardians. When one of these key players dies or becomes incapacitated, your entire plan is compromised. Yet many people fail to review these appointments regularly, only discovering problems when it's too late.

Beyond the obvious need to replace deceased individuals, consider whether your chosen representatives still make sense given current circumstances. Your brother who seemed like the perfect executor fifteen years ago may now be dealing with health issues, living across the country, or experiencing financial difficulties that make him unsuitable. Your designated guardian may have relocated, started experiencing marital problems, or simply aged beyond the capacity to raise young children.

Take a comprehensive approach when reviewing your trusted circle. Ensure you've named successor representatives for every role—backup executors, alternate trustees, secondary healthcare agents. Evaluate whether professional fiduciaries or corporate trustees now make more sense than family members for complex estates. Consider whether co-trustees or co-executors might provide checks and balances. Your estate plan is only as strong as the people executing it, and those people must be capable, willing, and appropriately positioned to fulfill their responsibilities when the time comes.

Relocation Across State Lines: Navigating Different Legal Territories

Moving to a different state isn't just a change of address—it's a change of legal jurisdiction that can significantly impact your estate plan. Each state has unique laws governing wills, trusts, probate procedures, estate taxes, property rights, and inheritance rules. A perfectly valid estate plan in your previous state may have gaps, conflicts, or inefficiencies in your new location.

Community property versus common law property states present particularly stark differences. If you move from a common law state like New York to a community property state like California, the fundamental nature of asset ownership changes for everything acquired during marriage. Estate tax considerations also vary—some states impose their own estate or inheritance taxes with thresholds far lower than federal exemptions. Your relocation might suddenly expose your estate to tax burdens you never anticipated.

Beyond the technical legal differences, practical considerations matter. Your out-of-state executor or trustee may face additional complications. Your durable power of attorney might not be recognized without state-specific language. Healthcare directives often need updating to comply with local medical regulations and facility requirements. After relocating, schedule a comprehensive review with an attorney licensed in your new state. They'll identify which documents need updating, which provisions require modification, and how to ensure your estate plan functions seamlessly within your new legal landscape.
