Yechiel Michel Epstein,
Translation:Arukh ha-Shulchan…
“ If two business partners claim the value of a pruta from one individual the case is heard even though each will only receive half a pruta, as the legal partnership is considered the claimant. Therefore, two who are not legal partners cannot claim a pruta from one individual. However, if an individual claims a pruta from two people the case is heard, because from his point of view it is a case meeting the minimum. ”
