For Marylanders creating or updating a will in 2026, four key issues are critical to avoid challenges: eliminate any ambiguity in all sections, ensure all pages and documents are properly affixed together, clearly identify all family members and beneficiaries, and have all signatures witnessed by required parties. Ambiguities, unattached pages, unclear beneficiary information, or improperly witnessed signatures can all provide grounds for costly and time-consuming challenges. Careful attention to these details helps ensure that a will is enforceable and minimizes the risk of litigation.
