較高收入一方可否向低收入一方 (約兩萬) 取贍養費?

You can request.

However, you must convince the court (or in a settlement situation, your soon-to-be ex-husband) that you are entitled in order to succeed.

For example, if you have a child (or children), and you are awarded custody (through court or agreement), you will be able to ask for maintenance for the child(children).

Also - both you and your soon-to-be ex-husband can be in mutual agreement for such maintenance by concession, such as giving up ownership of joint property in exchange of the money.

Bottom line - it depends on how you can prove.

Then why do you want to ask for more?

Again - this question has asked and answered.

You basically keep circling for the same issue.

Bottom line - your soon-to-be ex-wife has no case unless she can prove one.

婚姻一方有權向對方申索贍養費，分別供自己及或子女的的生活費。成功與否，視乎情況而定。雙方(目前及將來)的收入只是眾多考慮因素之一。其他因素例如索取方的(特殊)經濟需要，如涉及專業醫療費、子女教育費等的巨大生活開支。

贍養費是被養的一方可以索取。
假如夫有工作, 妻無工作, 妻可向夫索取。
假如妻有工作, 夫無工作, 夫可向妻索取。

而你的收入比夫高, 所以法官多數不會批准你收取贍養費。
甚至你的夫可以反過來向你收取贍養費。
所以忘掉這事情吧。
