Welcome back to the board and happy new year to you!
It wonderful that you and your husband have decided to get back together again and to move abroad so that you can really be your own couple without families interefering with your relationship. I would suggest talking to head hunters. I think they are the ones who have good portfolios of companies that are needing people to work abroad in the countries that you mentioned. If you go to the Britcham website for Hong Kong, they have a page for job seekers both with job offers and the possibility of uploading your CVs.
Think also out-of-the-box. Your husband trained as an engineer, but a lot of his skills and job experiences can also be used in other industries, too.
Since you are working in a law firm, start checking out which British law firms have offices in the countries that you mentioned.
Good luck to you both! I hope that you find something very soon.
