Match the label people will actually see
For a notice translated as “collect the pass at reception,” keep the original sentence and the name printed on the desk sign. Someone arriving at the building can then match the sign to the notice. Ask the issuer about a phrase when the two readings lead to different actions. Keep names of gates, counters and buildings as printed. Add a short explanation in the reader's language beside the original wording. A translated proper name can be hard to match to a sign.
Check words with consequences
In a notice, “collect,” “return” and “present” describe different actions. Have someone familiar with the context compare the translated line with the source. If one version seems to require surrendering an original document and another asks only to show it, contact the issuer before telling the household what to do.
Store the confirmed pair
Record the original sentence, agreed meaning, date and source. Label an informal translation as such so it is not mistaken for an official version. When a revised notice arrives, compare the original passages first. An old translation can remain fluent while describing an instruction that no longer applies.
