This is my response to you:
1. Before 2016 the laws did not permit a person to remarry before 6 months;
2. But recently the BHC allowed to remarry after 90 days: https://www.hindustantimes.com/mumbai-news/hindus-can-remarry-90-days-after-divorce-bombay-hc/story-8Lyg5ZRKSNdRFFOqVoIiOJ.html
3. So your spouse can only remarry after a waiting period of 90 days from the date of divorce decree;
4. Consult a local lawyer.
