poor credit mortgage financing

Will credit information be passed to other countries?

I live in britain but i was born in portugal where i wish to purchase a house. My credit rating here is poor and would prevent me from obtaining a mortgage there. Portuguese banks will only check for my credit details in the Bank of Portugal. Will the Bank of Portugal have any info on my foreign finances?

Credit profiles do not transfer from country to country.

There are many reasons why credit reports do not transfer from one country to the next. The main reason behind this is because of differences in national laws. Every country, and the European Union, has its own laws governing credit reporting and information use. In addition to legal barriers, there are significant contractual complications around how businesses in other countries would access reports, report and update information and respond to consumer disputes. There also are a number of technical issues around how information is collected, stored and shared that further complicates transferring your credit report.
