or الاجتماعية :

I'd go for community schemes to indicate one phrase, and strata to indicate another, so instead of being قسم المخططات الطبقية والاجتماعية it would be قسم الطبقات والمخططات الاجتماعية

schemes is translated as مشروعات in this case, and not مخططات

schemes can also be translated as برامج

قسم فض منازعات الملكيات المتداخلة

يرجي ملاحظة أن
strata
تعني هنا شكل من أشكال الملكية العامة المشتركة
وملاحظة أيضاً أن الترجمة الحرفية لا تنقل للقارئ معني محدداً

strata schemes, or strata plans, are the original forms of strata title. they are not completely dissimilar to the concept of traditional or 'green' title, in that the owner of a strata-titled property is the proprietor of everything within their property's boundaries. the main differences emerge in how a single property's boundaries are calculated within a strata complex, and that strata title allows for areas of 'common property' outside a single property's boundary, for which individual owners are jointly responsible. the main difference between a traditional title and a strata title is that strata titles can have horizontal boundaries meaning there can be several strata properties above each other. this is the basis for the term 'strata', which emanated from 'stratum' meaning layer.
Strata and community living often brings people of diverse interests and backgrounds close together. Disagreements and disputes sometimes arise. Tolerance, understanding of others and communication are essential to harmonious living. The Strata Schemes Management Act 1996 and the Community Land Management Act 1989 set out a process for resolving disputes. This includes mediation and formal orders by the Strata and Community Schemes Adjudicator and/or the Consumer Trader and Tenancy Tribunal.

الجملة توضح ما يقوم به القسم ولذلك يجب أن تصدر من شئ منتظم وشامل ودقيق
