What it is: the legal document that contains your written plan for what happens after you pass away. It lets you decide who receives your property, who will handle your final affairs (the executor), and who will care for your minor children if necessary.
What this means for you: without a will, Illinois law (intestate succession) decides who inherits your property — and not necessarily who you intended. A valid will gives your loved ones clarity and helps ensure your wishes are carried out.
What a will can do: name beneficiaries for specific items and the residue, appoint the executor, nominate a guardian for minor children, and set up a trust for young or vulnerable beneficiaries. It is the backbone of most estate plans.
Watch out for: a will only works after you die — it does nothing if you become incapacitated (use a POA for that). And a will must go through probate to be effective. Keep it updated after marriage, divorce, births, deaths, and big asset changes.
