Opelon LLP has published flat-fee prices for estate plans and offers free online tools that show San Diego County families what settling an estate may involve and cost before they hire anyone. The Carlsbad law firm focuses on uncontested probate and trust administration and is known for explaining the process in plain English.
The firm built a library of California probate guides and free tools, including a probate fee calculator and a probate decision tool. These resources help families understand their options before they commit. More than 250 San Diego County families have been guided through probate, and more than 700 California trusts have been drafted.

Managing Partner T. Owen Rassman holds an LL.M. in Taxation and was selected to Super Lawyers from 2023 to 2026. The firm grew out of Rassman’s Carlsbad practice, formerly Rassman Law. Much of its probate work is with families who never expected to be in court.
Rassman said the date of death controls which limit applies, and families often don’t realize that. Two estates of the same size can take very different paths depending on when someone passed away. “The date of death controls which limit applies, and families often don’t realize that,” he said. “Two estates of the same size can take very different paths depending on when someone passed away.”
Opelon serves adult children, surviving spouses, and families in San Diego County who have just lost someone and are handling an estate for the first time, often while grieving and unsure where to start. The firm also serves individuals and couples planning ahead so their own families avoid that uncertainty. For families who want to see what uncontested probate and trust administration involves, the firm’s website offers guides and tools at no cost.
The free 15-minute phone consultation tells families whether their matter is work the firm handles, what it costs, and what the next step is. This aligns with the firm’s transparency approach: published flat-fee prices for estate plans and online tools that show potential costs before hiring.
Rassman’s LL.M. in Taxation and repeated selection to Super Lawyers reflect the firm’s focus on estate matters. The firm continues to guide families through probate and trust administration while providing resources for those planning ahead.
