Question about Previous Titles

I need some assistance from anyone out there who's more familiar than myself with locating information in Puerto Penasco, Mexico.  A few years ago, my husband and I purchased a condo at The Princessa.  We sold the property and have since lost our records in regards to this property.  How do I obtain a title or deed of trust for a property that was sold a number of years ago.  If you know...please email me at dtw306@aol.com
