In Ontario, when you marry, you automatically revoke your will unless you have made specific provisions not to do so. The reason for this is that your spouse and/or children should not be disinherited simply because you forgot to update your will to reflect your changed circumstances. You can have a will drafted that is in contemplation of marriage, or you can revive a prior will after marriage, but you must take specific steps to do so. Otherwise, you will fall into the rules of intestacy in Ontario, and your next of kin will inherit according to rigidly defined rules. If you are planning to marry, you should consider speaking to someone about what will happen to your estate.
