Article 1220. The remission of the whole obligation, obtained by one of the solidary debtors, does not entitle him to reimbursement from his co-debtors.
Artikulo 1220. Ang pagpapatawad sa buong pagkakautang ay nakuha sa pamamagitan ng isa sa magkakasamang mangungutang wala siyang karapatan na manghingi mula sa kapwa niyang mangungutang.
There is nothing to be reimbursed because he did not spend any money, the remission being a gratuitous act.
Remission, it must be borne in mind, is essentially gratuitous. Note that this Article applies only when the whole obligation is remitted.
Example:
A and B are solidary debtors of C to the amount of P1,000,000. C remitted the whole obligation when A offered to pay. A here cannot get any reimbursement from B since after all, A did not pay anything to C. To allow the contrary would be to induce fraud and to countenance partiality.
