To be valid, your will must:

✒️Be in writing,
✒️Made by you while you are mentally capable and not being coerced,
✒️Signed at the end of the document by you and two witnesses, with all three of you being present to see each other sign, and
✒️Intended by you to take effect as a will

However, if your will doesn't meet all of these requirements then a court may still declare it a valid will in certain circumstances.
