Co-applicant pay half loan

no. he can't clear his share of the loan. it is the liability of both the borrowers to pay the loan jointly. so there is no partition of loan liability in between them. they are jointly and severally liable to pay. if anything paid against the load that be adjusted to the outstanding dues of loan and remaining balance be fresh outstanding against both of them.

If the Liablities are specified and defined then he can clear away ; The joint laiblity would clear upon full payment

Thanks a lot for your valuable inputs.

There is a possibility of requesting the bank to substitute the co-obligant with another person with more creditworthy, and if the bank, present borrower and the new co obligant agree there is a possibility of completely getting exonerated from entire liability of the present co-obligant.  It all depends on the responsibility of co-obligant,in present loan whether he is also beneficiary or stood as co-obligant with relationship or due to his designation (office bearer/director) or as his property is offered as security for the present loan etc.,

Both the borrower and co-borrower has to repay entire outstanding loan amount jointly and severally, which can not be bifercated as 1/2 share.

No is the answer . once pay back entire amount of loan is must.
