To answer your first question, if she is not in a state of mortal sin, she can receive the Eucharist. Even if she was in a new relationship, a dating relationship, she could receive, but if she was remarried she could not.
Secondly, she does not have to contact her husband, the church will do that for her, the tribunal, that is.
It is not like a divorce where the two parties have to seperate material goods or meet up in court.
Sorry to butt in here, but this is not entirely correct, she is not allowed to “date” Until she has applied for and received a decree of nullity, the decree proves she is not still ( actually never was) married within the eyes of God,Up and until that decree she is assumed still married and therefore cannot “date”
as far as contacting the ex goes you (person filing)
does not have to contact, the tribunal will handle all that, Its a lengthy process, fill out paperwork, wait, then suddenly you recieve a letter stating they are sending out witness questionaires ( you will think dang I would have thought that part was already done) then you wait , and wait some more about the time you think they totally have forgotten about you ( 8 months after filing or so) you call them up and they say OH we just sent you a letter about it all lol next day letter in box telling you has or has not passed local tribunal and is headed to higher tribunal for accuracy AND
basically appeal, then a month later usually done you get paper saying you free like the birdies, or not…
BUT you do not have to contact the other yourself
Many Saints have been divorced, so dont see it as the end of the world.
Hope that helps , get the papers filed asap its a long drawn out process
good luck
p.s. for the record now that I have read a few other posts, she cannot “date” or pursue a courtship, or relationship of that nature till decree of nullity is granted and ratified, she is still married in the eyes of the church up until that decree is ratified. this is also emphasized on the paperwork she will be filling out as well…
The church also recognizes that Many “divorced persons” do not even seek a nullity decree until they have already entered into another relationship or plan to remarry, they will give you all the proper paperwork,instructions etc and what you can do IF you are in a relationship already.
