Filing I-130 with new married name or maiden name?

[nj.saph]

I'm a LPR (female) and just got married to my foreign spouse. In our marriage certificate, I changed my last name to my husband's name. However, I have not changed any document (including SS card, green card, passport, driver's license) to my new name and I do not intend to do so for another year or so. I am filing a I-130 for my husband and I'm not sure whether to use my new last name to file or my maiden name.

Can someone please let me know how to go about this? Thanks in advance!
