In general, wills can be established more rapidly and more affordably than trusts and are ideal for individuals whose wealth portfolios are relatively simple. While wills allow you to appoint guardians for your minor children and ensure that your property is distributed among your loved ones as you see fit, they are far less flexible and versatile than trusts. Wills must also pass through probate court under the oversight of an executor to become legally valid. If the probate process is not handled efficiently, the result can be time-consuming, expensive and stressful for everyone involved.
