When deciding whether to have a living trust, be sure you know what your goals are and whether this is the best way to achieve those goals. Are you trying to reach beyond the grave and control how your heirs receive and spend money? Are you trying to avoid probate? If so, why? Some states probates should be avoided because of the cost and delays, but in other states, probate is quick, easy and informal.
What assets are going to be in the trust? What assets are better held in a different form? You need to answer these questions. A living trust does not protect assets in the trust from creditors and sometimes exposes assets that would otherwise be exempt from creditors to creditor claims.
Trusts are one area I recommend consulting a lawyer who is well respected in the estate planning field.
