XVII. Macario bought a titled lot from Ramon, got the title and took possession of the lot. Since Macario did not have the money to pay the taxes, fees and registration expenses, he was not able to register the Deed of Absolute Sale. Upon advice, he merely executed an Affidavit of Adverse Claim and had it annotated at the back of the title. A few years after, he received a Notice of Levy on Attachment and Writ of Execution in favor of Alex. The notice, writ and certificate of sale were annotated at the back of the title still in Ramon's name. Alex contends that since the Affidavit of Adverse Claim is effective only for 30 days from the date of its registration, then its validity has expired. Macario posits that the annotation of his adverse claim is notice to the whole world of his purchase of the lot in question. Who has the superior right over the disputed property - Macario or Alex?
