2. On March 15, 2014, Jun borrowed from Chris the amount of P350,000.00 payable on March 15, 2016. As security for the loan, Jun mortgaged his 90-square meter lot in Dasmarinas, Cavite, which was valued at P500,000.00, to Chris. On February 28, 2016, Jun's cousin, Lucille, paid Chris P350,000.00 without consulting Jun about it. When the obligation, however, fell due on March 15, 2016, Jun was already insolvent. Arvin, the husband of Lucille, now seeks to foreclose Jun's 90-square meter mortgaged property, so he and his wife can recover the P350,000.00 payment advanced by Lucille to Chris. Can Arvin foreclose on the mortgaged property? -> Art. 1237
