EREÑETA V. BEZORE (November 26, 1973)

FACTS:
Emilio Camon is a lessee of sugar plantation Hacienda Rosario. ½ of the plantation is owned by Petronila Alunan vda. De Santa Romana, Amparo Santa Romana and Alberta vda. De Hapon while the other half is owned by the appellants Bezore et al. Camon died and his widow Conception Ereñeta filed a petition for the grant of the letters of administration of the estate of his husband. Bezore at al. filed a claim against the estate of Camon amounting to P64,165 for sugar allotments, palay, allowances and rental.
Agreement to sell - whereby Bezore et al. agreed to sell their share to Romana et al.
Release and waiver of claims – Romana et al. released Camon from all the claims that may have accrued pertaining to the 2/4 pro indiviso share in Hacienda Rosario.
Deed of Sale- Bezore transferred to Romana et al. all their rights, title, interest and participation whether accrued or accruing in their 2/4 pro indiviso share in consideration of P78,000.

ISSUE:
WON the appellants have the right to claim over the estate of Camon.

HELD:
Appellants don’t have the right to claim over the estate of Camon because of the waiver of claims made by Romana et al, who are the now owner of hacienda Rosario.
The claim of the appellants that the waiver is not valid because it was made before the rights transferred were even sold to the Roman et al is of no merit. The waiver is subsequently cured by the sale of the rights of the appellants to Romana et al.
The court also finds no merit to the contention of the appellants that the sale has infirmity because of cheap consideration of 1,300 per hectare. Inadequacy of cause in a  contract does not of itself invalidate the contract.
