Trusts are sometimes called revocable trusts or inter-vivos trusts. A will must be administered through probate whereas a trust avoids probate. In addition, a will becomes public record whereas a trust remains private. A trust must be properly funded to be effective. Funding simply means that the assets that you wish to be distributed must be titled in the name of the trust.
Some people make the mistake as having a trust prepared but they fail to fund the trust.
Once the trust is properly funded it can transfer your property without attorneys or the court system. Furthermore, when you die your property can be transferred without attorneys, the court system or probate. All of which could be timely and costly. Not if you have a revocable trust. A revocable trust allows you to transfer all of your assets to the trust but continue to use and manage them during your lifetime.
