I have a custom object called Partner__c
It has two lookup relationships to Contact
standard object as shown below.
But in Page Layout I am unable to see the Contact object available in the Related List.
I assumed that if you have a lookup relationship in Y object to X object, then X object can be exposed as a Related List to Y object.
For Example
Y.Foreign_Key = X.Primary_Key
Am I wrong ?

Since the lookup is from Partner to Contact, you'll see only fields on the "child" side of the relationship. If you go to Setup > Customize > Contacts > Page Layouts, you can add both related lists (Billing Partners and Business Partners, or whatever you called them) to your contacts' related list section. From your example,
Y.Foreign_Key = X.Primary_Key
,Y.Foreign_Key
appears a field onY
, but appears as a child relationship (related list) onX
.
