More serves as undersheriff of London from 1510 as a dated civic legal office
In 1510 More became one of London’s undersheriffs, a civic legal office he held into the 1510s. It is not the 1529 chancellorship as a second copy. In the causal graph this event weakens Judicial independence erosion (court capture), a driver that strengthens Rule of Law Gap from the Highest Governance Score — an improving welfare path.

In 1510 More became one of London’s undersheriffs, a civic legal office he held into the 1510s. It is not the 1529 chancellorship as a second copy.
Context
History of Parliament Online and Britannica independently date the 1510 undershrievalty.
Thomas More’s documented role is bounded by other offices and collaborators named in the sources below.
Conventional years are 1478–1535. Surviving public files are later parliamentary biographies, TNA calendars, HRP Tower pages, the Yale More tradition, and encyclopedias. More did not typeset those later pages. 1935 canonisation is posthumous and is not a Fact.
Why it matters

The City appointed an undersheriff. He sat in the sheriffs’ court. Complex civic office, not a later chancellorship twin.

What the sources establish
History of Parliament Online and Britannica independently describe the 1510 London undersheriff post.
Established: More was undersheriff of London from 1510. Not established: a unique later fair-trial series from that court.
Thomas More did not file a later UNESCO form, a later Loeb colophon, or a later museum label as a personal act. A City court is not Tower Hill. Keep 1535 as the killing.
