Estate planning instruments, including trusts, can be used to avoid probate.
If some information you have seen or heard has led you to believe a Will does not have to go through probate, you have been mislead, according to TC Palm in "Common misconceptions about wills and trusts."
Sometimes misconceptions begin with TV shows or movies that are just that – TV shows and movies. They do not have to present the law as it actually is.
Another way to come up with a misconception is that in some states, if an estate is small enough, then it does not have to go through probate. Usually, these are very small estates with very few assets. It certainly is not the norm. Someone with good intentions probably had a relative or friend who passed away with few assets and as a consequence, their Will did not have to go through probate.
However, most Wills do have to go through probate. They need to be submitted to the court and approved. The probate court then oversees the administration of the estate as conducted by the executor. If you want your estate to avoid probate, what you need is a trust.
An experienced estate planning attorney can advise you on creating an estate plan that fits your unique circumstances.
