it might sound weird, but here is what I found under Mirriam Webster's Dictionary of Law:

Main Entry: per·pet·u·ate
Pronunciation: p&r-'pe-ch&-"wAt
Function: transitive verb
Inflected Forms: -at·ed; -at·ing
: to preserve or make available (testimony) for later use at a trial by means of deposition esp. when the evidence so gathered would be otherwise unavailable or lost
NOTE: Courts will not allow the perpetuation of testimony at a pretrial proceeding if it appears to be an attempt to fish for useful material. —per·pet·u·a·tion /p&r-"pe-ch&-'wA-sh&n/ noun

If the word is used differently, i.e. stating again and again, you might also consider "reiterate" as an alternative.
