Hi, thank you for your question. Unfortunately, as you are joint tenants you are both entitled to occupy the property and given that you have already paid the rent, there will be no automatic liability for her to make any contributions. However, as there appears to have been agreement for her to make some contributions you should formally and in writing remind her of her obligation under your agreement regarding contributions and if she continues to fail to contribute you can put her on notice that you will seek a money claim to court for her share of the contributions.
I hope this assists you. If you found this information helpful please provide a positive rating using the stars at the top of this page. I will not be credited for your question without a positive rating. Thank you
