Gaps the default rules leave
Without a will, New York's inheritance rules follow legal relationships, so a stepchild who was never adopted generally receives nothing from a stepparent's estate. A will or trust can include stepchildren by name, and the wording matters, because a gift to 'my children' may not cover them. A child's other parent also comes into the picture, since a minor who inherits needs someone to manage the money, and a parent from an earlier relationship may otherwise end up controlling it. In blended family estate planning the documents usually have to do more of the work, because the default rules were not written with these households in mind.
Old paperwork to track down
Account beneficiary forms are where blended families most often find surprises, such as a former spouse still named on a retirement plan or a life insurance policy. New York law generally revokes provisions for an ex-spouse after a divorce, but that rule does not reach every account, and some federally governed plans pay whoever is listed on the form. Pull the current designation for each account and policy, along with any divorce judgment or custody order that sets obligations. If you signed a will before your current marriage, bring it, since in New York a later marriage does not by itself rewrite an existing will. Note each child's age and which parent they live with.
Choosing guardians and money managers
For minor children, a will can nominate a guardian, and in a blended family that choice often needs explaining because a surviving biological parent usually has a stronger claim to custody. Separating who raises a child from who manages that child's inheritance is often useful; a trust can let a trusted relative or friend control the money even if the child lives with the other parent. We also talk about whether each child should be treated the same or whether different needs justify different shares. A first conversation usually ends with a list of designations to update and a plan for who holds each role.
