4 weeks is plenty of time to get married
Lanie and I got married last Christmas/New Year and even with two sets of public holidays it was pretty plain sailing
Two things though
Depending on where you want to get married your gf may or may not be required to attend a pre-marital seminar. Lanie and I got married in Mindanao and this didn’t appear to be a requirement – infact it was never mentioned
If it is required I’m not sure if only she is required to attend it or whether you must attend it as a couple . maybe some other members on the forum can advise
Also the 10 days wait - you can ask the judge / mayor to waive this period , to say 5days
Hope this helps
Good Luck !!!!
