2,949. Can One Absolve Valuations?

Hilchos Arachin Vacharamin 1:16

Valuations are set based on the age of the one whose valuation is being committed, not based on the age of the one making the commitment. For example, if a 20-year-old tells a 60-year-old, “I commit your valuation,” he is obligated in the valuation of a 60-year-old. If a 60-year-old tells a 20-year-old, “I commit your valuation,” he is obligated in the valuation of a 20-year-old. The same is true in all comparable cases.

Hilchos Arachin Vacharamin 1:17

The words of one committing a valuation must match his intention, as is the case with all other vows. One may approach a Torah scholar to annul a commitment for a valuation or a person’s value, just as one may seek to annul other vows and consecrations.
