Why You Need Legal Help in Capacity & Undue Influence Litigation

When questions arise about whether a will, trust, or property transfer was made freely and with full understanding, disputes can quickly escalate into capacity and undue influence litigation.

These cases often involve allegations that a vulnerable individual lacked the mental capacity to make decisions—or that they were pressured, coerced, or manipulated by others.

The stakes are high: the validity of an entire estate plan, trust, or property transfer may hang in the balance. Without experienced representation, families risk losing inheritance rights, seeing assets diverted unfairly, or watching years of planning unravel in court
