In this world, marriage is nothing but an association between to people. My wife, Hazar Oyen, and I can not share the land I purchased nor can she build on it.
It turns out I had to create a group (which currently costs L$100), add her to my group and set the group in the land properties. She then had to "activate" her group so she could freely build on the land.
My user provided the following information for all users in his world:
Creating a group in Second Life is simple and easy, but will currently cost you L$100 ( $0.68 USD ).
1. Right click your avatar and select "Groups..." or select "Edit -> Groups..." from the menu.


2. On the Groups window, select "Create".

3. Fill in the name and fill in the charter for the group in the "Group Information" window. The other tabs and options will remain unavailable until you create the group. If you have a group/family picture, you can associate it to the group either now or later.

4. Once all the information has been filled in, select "Ok" or "Apply". You will be presented with a dialog box asking if you want to spend the L$100 to create a group.

5. You should now have your "Group Information" window with the tabs and options unlocked and the "Members & Roles" tab selected. Select "Roles". Select "Officers" and select "Delete Role", we do not need this role. Select "Create new role" and enter Wife/Husband/Partner, for this tutorial I will use "wife". Under "Allowed Abilities", give your partner all the "Parcel Powers", "Parcel Access" and "Parcel Content". Also select "Manipulate" under "Object Management" to give them permissions to move things around on the land. Select "Apply"

6. Select "Members" and select "Invite New Person..." for the "Group Invitation" window.

7. Select "Open Person Chooser" and select your partner. Select the "wife" role down near the bottom and select "Send Invitations".

8. Now right click your land and select "About Land..." or select "World -> About Land..." from the menu.


9. In the General tab, select "Set..." next to Group: option.

10. In the Options tab, uncheck "All Residents" and check "Group" for "Create Objects", "Object Entry" and "Run Scripts".

That's it, your partner in Second Life should now be able to create prims on your land without any problems. Repeat the above steps 6-8 to make a role and assignments for "Friends" or "children".
