Cyfraith Cytundebau yw hyn, yn ymwneud â dylanwad gormodol (undue influence).

Mae'n berthnasol i ddyletswydd sydd ar fanc pan fydd gwr a gwraig yn ymrwymo i gytundeb, ond bod amheuaeth bod un ohonyn nhw dan bwysau i wneud hynny. (Dwi'n cymryd mai er hwylustod mae 'wife' a 'husband' yn cael eu defnyddio yn y darn isod, ac y gallai fod y ffordd arall)

When is the bank put on inquiry?

A bank is put on inquiry when a wife offers to stand as surety for her husband’s debts.  This particularly applies where the transaction is not to the wife’s financial advantage and where there is a substantial risk that the husband has committed a wrong that would entitle the wife to set the transaction aside.  These two factors provide the underlying rationale for the bank to be put on inquiry
