Estate planning is more than just jotting your wishes down on a notepad. But, if you wish to avoid probate, you will need more than just a will. A will's primary function is to let the court know your wishes. There are other estate planning documents, though, that can help keep your estate out of probate. One of those is a revocable living trust.
Some people worry that putting assets into a revocable trust means that they won't be able to do anything with those assets. However, the person who creates a trust has complete power to change it at any time. You can sell an asset, list a beneficiary to inherit it and even decide that you want someone else to have it after you pass away.
