I am not qualified to advise you further on Miller trusts. Along with a number of other estate planning attorneys in El Paso I refer people to Julia E. Merkt, immediate past president of the Texas Chapter of the National Academy of Elder Law Attorneys. Julia is especially qualified as an expert in Medicaid elegibility questions. I'm a long standing resident of Texas, and have put this off long enough. Vicki Vicki, the only forms we post on this site for free downloading are advance directives such as powers of attorney and medical powers of attorney.
Wills are another matter entirely.
There's a reason you hear about will contests in court all the time, but never about power of attorney contests. It's because wills have to be individually drafted to avoid problems. An executor must be named. One must consider providing for a bequest that goes to a minor, either because a minor is named, or because the minor's parent predeceases the testator. That means voided.
