A later-life divorce (sometimes called "gray divorce") often means rebuilding both your social network and your legal planning documents from scratch, since a spouse was likely your default agent for everything.
Update your documents immediately
Power of attorney, health care proxy, and beneficiary designations naming an ex-spouse should be revised as soon as possible — these don't update automatically just because a divorce is finalized.
Rebuild community deliberately
Many post-divorce friendships were "couple friends" tied to the marriage — expect to invest in some new connections rather than assuming existing ones will transfer cleanly.
