While sharing title to property may avoid probate after your death, naming “joint tenants” may have a number of adverse consequences. In effect, adding a joint tenant to your home deed means that you have now gifted a portion of that property to those named. And when you make gifts in excess of $14,000 in value within a calendar year to someone other than a spouse, the IRS requires you to file a gift tax return, and in some cases pay gift taxes. When gifting an interest in your home to anyone, you also are endangering your own financial security.  If your new co-owners have creditors or are involved in a divorce, your assets will be at risk.  Furthermore, such a transfer may jeopardize certain property tax and other exemptions you enjoy as a senior, veteran, or homesteader.
A better idea is to create a Living Trust and name your children as beneficiaries of the Trust after you die. This has the advantage of avoiding probate, yet it gives you total control of your house prior to transferring ownership. You can also change beneficiaries if you so desire, and also provide for the circumstance if one child predeceases you.
