Superwang, your friend should post his story and question here if he is serious about getting serious answers.
The information you have provided, and maybe even know, is not detailed enough for a meaningful response.
Based on my experiences with two friends who were in similar positions, and based upon what they told me, the starting position for your friend is at this time and in principle zero.
In order to make any positive movement from that position your friend needs legal advice.
Did your friend have anything agreed in writing and signed by his wife and himself?
Are there any children involved? In a UK divorce the respective needs of any children come first in any final hearing.
When you say a UK divorce took place:-
- who was the petitioner?
- are you sure that the divorce has taken place? (absolute issued?)
- who has suggested the the house & lot in the Philippines is a viable asset for your friend? and on what basis? Is he named on any official documents?
