An address is a pointer, not a sentence
Latvian is the language required for documents used in Latvia, and nearly everything on your page is rendered into it. Addresses are the exception that proves the rule. They are strings that identify a physical place, and their value lies in being matched against a register or a map. Rendering them into another language destroys precisely the thing they were printed for.
The labels change, the contents do not
What does get translated is the frame around the address: the words announcing whose address it is and why it appears. A reader in Latvia needs to know they are looking at a place of registration rather than a correspondence address, and that distinction lives in the label. The line beneath it stays as printed, so both halves of the page do the job they were meant to do.
Getting the address right at source
A faint or cropped address is worth fixing before translation rather than after. Where the paper is a birth, marriage or death record, Manchester Register Office at Heron House, 47 Lloyd Street, Manchester M2 5LE issues fresh certified copies of civil records, printed cleanly enough that every line of an address can be read without guesswork. That removes the most common cause of a query part-way through a job.
Rate and schedule
Work is charged at £25 for each page of the source, so the total follows the sheet count rather than the number of names and addresses crowded onto a page. Standard turnaround is 2–4 business days from a legible scan, with 24–48 hours where the express route is used. Counting first means the quote is settled before anyone starts writing.
