Can I file my Federal and Possibly my State as Married

[insanity2468]

My girlfriend, who is US citizen and lives in Ohio, had to go back to Italy to obtain her inheritance.  When she got to Italy she found out that her father had put in a requirement in the Will requiring her to be married to obtain the inheritance.  We got married on October 8, 2019, in Abstentia, with our lawyer standing in for me for the wedding.  After the wedding their were complications which resulted in her having to stay in Italy past December 31, 2019.   So as a result she has not established residency in Delaware with me.  Can I still claim Married on the Federal taxes.  If I can what do we do about the State taxes for Delaware and Ohio, cause there is no date of residency for her for Delaware.

Thank you!!!!!

File as married jointly for Federal and State.
 If one spouse is a resident of Delaware and the other is not, you can file either a resident or nonresident return, whichever is more beneficial to you.
