・We got married officially.
・We were formally married.

「正式結婚」可以用英語 We got married officially. 或 We were formally married. 來表達。

After living together for a long time, we finally submitted a marriage registration and got married officially.
（我們已經同居很久了，終於辦理了結婚登記，正式結婚了。）

We almost broke up several times, but happily we were formally married.
（我們有幾次差點分手，但現在我們正式結婚了。）
※ happily（高興地，幸福地,，幸運地，等等）

以上供你參考。
