## Database Query Details

### Relationships Loaded for Trusts
```php
Trust::find($id)->load([
    'beneficiaries',              // TrustBeneficiary
    'assets',                     // TrustAsset
    'allowances',                 // TrustAllowance
    'gifts',                      // TrustGift
    'donations',                  // TrustDonation
    'administratorAllowances',    // TrustAdministratorAllowance
    'guardianAllowances',         // TrustGuardianAllowance
    'trustees',                   // TrustTrustee
    'caretakers',                 // TrustCaretaker
    'client.familyMembers'        // Client relationships
]);
```

### Relationships Loaded for Wills
```php
Will::find($id)->load([
    'client.familyMembers',
    'client.assets',
    'beneficiaries',              // WillBeneficiary

## Security Considerations

✅ **Authorization Checks**
- User must be assigned lawyer or referred lawyer
- Unauthorized access returns 403 error

✅ **Data Validation**
- Safe field access with null coalescing
- No unescaped user data
- Proper type casting

✅ **SQL Injection Prevention**
- Using Eloquent ORM for all queries
- No raw SQL in preview method
- Parameterized relationships

---

## Performance Notes

- **Eager Loading**: Uses `->load()` to prevent N+1 queries
- **Collection Handling**: Efficiently converts collections to arrays
- **Conditional Rendering**: Sections only render if data exists
- **Memory Efficient**: No unnecessary data processing

---

## Future Enhancements

🔮 **Potential Improvements**
- Export to PDF functionality
- Digital signature support
- Version comparison view
- Archive/historical versions
- Multi-language support
- Signature page customization
