Question

In 2010, Amalia and Carlos got married. They decided to enter into a marriage settlement to determine the property regime that will govern their marriage. They opted for a separation of property regime. The settlement was duly notarized and registered.

After 5 years of marriage, Amalia inherited a large sum of money from her late grandmother's estate. She used a portion of the inheritance to buy a luxury condo unit in her name alone. Carlos contributed equally to the household expenses.

Unfortunately, their marriage started to deteriorate due to irreconcilable differences. Amalia and Carlos are now contemplating divorce and are concerned about the ownership of their properties. They seek legal advice regarding the separation of property regime, as provided in the Family Code.

Discuss the legal effects of the separation of property regime on the ownership of the luxury condo unit acquired by Amalia using her inheritance. Consider the provisions of Arts. 143-146 of the Family Code and provide a comprehensive analysis.
