Contested probate can be a complex and costly process, as it involves legal proceedings and potentially multiple rounds of litigation. The cost of contested probate will depend on a variety of factors, including the complexity of the case, the value of the assets at stake, the number of parties involved, and the length of time the case takes to resolve. In general, contested probate cases can involve significant legal fees for lawyers, as well as other expenses such as court costs, expert witness fees, and other costs associated with preparing and presenting a case in court. It is not uncommon for contested probate cases to cost thousands of pounds, or even more in some cases. It is important to keep in mind that the cost of contested probate can vary widely depending on the specific circumstances of the case. It is a good idea to consult with a contentious probate solicitor to get a better understanding of the potential costs involved.
