Trusts and Estates
Timothy O’Brien brings a wealth of legal, financial, and accounting knowledge to his analysis of his clients’ needs. For more than two decades, Tim, a principal in the firm’s Estates and Trusts Group, has advised clients on a wide range of estate and trust issues. He advises clients on their estate planning options and makes recommendations to avoid unnecessary taxes. He also assists with the administration of estates, trusts, and guardianships.
When necessary, Tim will seek court intervention to resolve disputed matters, whether the dispute involves a will contest, the validity of a trust agreement, or the recovery of misappropriated assets. Known for his tenacious advocacy, Tim doesn’t shy away from complex or contested matters. In fact, Maryland judges regularly appoint Tim as a successor personal representative for estates that have been mismanaged by previous fiduciaries.
Tim has helped countless families navigate difficult situations, such as recovering estate assets that have been misused, settling tax liabilities with the IRS, and protecting assets for future generations.
In his spare time, Tim is a student of Irish history and an avid baseball fan, and has served as the treasurer for local, state, and national political campaigns.
